circular in cross-section and formed prefer` l ably kby a circularlybent sheet or'plate of rolled steel and has its vertical edges abuttingagainst each other, as at 12, Fig. 3. Said member Vl0 extends at itslower end into and is embraced by the upper nular downwardly yflaringsteel base" 13 adapted to rest on a floor to which saidfbase maybeVsecured in any approved Qmanne'r. Themember l0 andthe baselSarerendered rigid with each other in anv ner, as, for instance,securing vtheircontiguous or adjacent portions together., The member l0is embraced ak steel colla-r la, Vand said vpartsarefwelded together orotherwise T The member lO-hastwo lateral bolt-holes l5 arranged saidmember and -in line-endwise, `as shown inrigs. -l and 2 and said memberis provided below and-al short distance from each hole llwith a lateralholef l6i f wA horizontally arranged bolt has its shank y l Y 17extending 'loosely through the bolt-'holes l5 inv the `lvtubularfmemberl0y andgfl'oosely plates A whicheX- tend circumferentially of said shankatopposite sides respectively and next externally lof said tubularmember.` Y Said shank leX- of the -adjacent clamping plate,and a nut l8is screwed onto said end at` and overlaps said side of said pla-te. Thebolt is provided atlits other endl witha square head lQwhich ,L69 end ofan ansV 65 approved `IIian- 3'5 by'welding or otherwise `tends'at itsvfree end beyond .the outerside is embraced by a correspondinglyinternally shaped vportion a'of the clamping plate adjacent said headand has its inner end face overlapping vthe outer side of the centralportion of said platey so that the vbolt can not turn within theclampingplates A dur- 4ing the manipulation of the nut V18and I tubularmember-20 'which'.is circular inV xhere remark that .saidplates arecross-section and extends intothe Vrel-atively I0 `from above and.substantially corresponds: in external diametenwitli -the internaldiameter lof the The Vadjustable of a circuhas its vertical edgesabutting against each other, as at 22, Fig. 3. T he adjustable member 2Oextends above the relatively stationary member 10 in any position ofsaid adjustable member and is provided at its upper end with a head Q3employ-ed in carryingla desk-top, table, seat or other object (notshown). The head 23 Vconsists of an upwardly flaring steel member whichembraces the upper end of the tubular member 20, and said parts arerendered rigid with each other in any approved manner, as, for instance,by welding or otherwise securing their contiguous or adjacent portionstogether. The adjustable member 20 has two slots 25 which extend fromthe lower extremity of said member vertically upwardly a suitabledistance and are arranged at opposite sides respectively of said memberand in line laterally. Said slots register with the bolt-holes 15 in therelatively stationary member 10 so that the bolt-shank 17 extendsthrough the slots.

Each clamping plate A is provided bef low the bolt-shank 17 with a lug27 which projects inwardly through the adjacent hole 16 in the tubularmember 10 and through the adjacent slot 25 in the adjustable member 20and throughor into a lateral hole 28 formed in an abutment-plate Barranged internally of Said adjustable member opposite the aforesaidclamping plate. That is, two abutment plates B are arranged internallyof opposite portions respectively of the adjustable member 20, oppositethe clamping plates A, and extend circumferentially of the bolt-shank 17which extends loosely through said abutment-plates which are spacedlongitudinally of the bolt and form the end-portions of a brace which isarranged internally of the aforesaid adjustable member and below theupper end of the relatively stationary tubular member 10 and comprises across-bar C which is inverted-U-shaped in cross-section and arrangedinternally and transversely of the said adjustable member andlongitudinally of the bolt-shank. 1t will be observed therefore that thecross-bar C forms the central portion of said brace and said barstraddles the bolt-shank 17 and extends and is interposed between theabutment-plates B which overlap opposite end faces respectively of saidbar. Preferably the bar C engages cavities 29 formed in the plates B,and the bottoms of said cavities form seats for said bar which istherefore supported from said plates.

By the construction hereinbefore described, it will be observed that thebolt is provided with means,-viz. the nut 18 and the bolt-head 19,-whereby the clamping plates A by manipulating the nut as required to`tighten 1t against the adjacent clamping plate are caused to clampinglyenmember 10 and clamp the adjacent portions of both tubular members 10and 20 against the abutment-plates B and consequently against the endsof the internal brace comprising said abutment plates and therebyefliciently secure the adjustable member in the desired adjustment. Uponmanipulating said nut to loosen it said adjustable member is renderedfree to be rcadjusted vertically. that the cross-bar C and theabutmentplates B very effectually brace the adjustable member 2Ointernally when said member has been secured in the desired adjustment,and that in parts preparatory to the insertion of said adjustable memberinto the relatively stationary tubular member 10, said plates andinterposed cross-bar are placed in position within said member 10 andarranged with the holes`28 in registry with the holes 16 in said` member10, whereupon the clamping plates A are applied with their lugs engagingsaid holes 16 and 2S so as to cause the abutment-plates B and theinterposed crossbar to be supported from said Yclamping plates,whereupon the bolt is inserted and thereupon the nut is screwed onto thebolt, and lastly the adjustable member 2O is ingage the tubular Vsertedwithin the relatively stationary member 10, and to facilitate theinsertion of said adjustable member the abutment-plates B are rounded attheir top edges, as at 30, Fig. 1.

Vhat 1 claim is 1. ln an adjustable pedestal, the combination, with avertically arranged tubular member provided with a base, and avertically arranged and' vertically adjustable tubular member mentionedtubular member from above, of two clamping plates arranged at oppositesides respectively and externally of the firstmentioned tubular member,two abutmentplates arranged vinternally of the aforesaid adjustablemember at opposite sides respectively of said adjustable member andopposite the aforesaid clamping plates, a crossbar interposed betweenthe abutment-plates, and means for causing the aforesaid clamping platesto clamp the adjacent portions of both tubular members to theabutmentplates, each clamping plate having a lug projecting into theadjacent abutment-plate.
